MOUNTING FOR CYLINDRIGAL BRUSHES.

Application filed April 18, 1921. Serial No. 462,433.

To all 107mm 712? may concern,

Be it known that I, LAURITS Hanan; NT DLSEN, a subject of the King of Denmark, and a resident of Kolding, Denmark, have invented a new and useful Improvement in Mountings for Cylindrical Brushes, of which the following is a specification, the principle of the invention being herein explained and the best mode in wh ch I have contemplated applying that prlnciple, so as to distinguish it from other inventions.

The present improvements, relating, as indicated, to brush mountings have more particular regard to the provision' of a mountingfor so-called cylindrical or rotary brushes whereby the latter may be directly secured onto a shaft or arbor without requirin to be slipped on endwise over such shaft or arbor. In polishing machmes there are frequently mounted a series of brushes between the bearings wherein the supporting arbor is journaled, and inorder to replace or exchange any one of these brushes'the entire shaft has to be taken down and frequently a number of brushes removed in order to get at the particular The principal object of the present invention, as stated, is to do away with th1s necessity, time being accomplished by a special construcproved mounting is also of more general utility in that it permits of the ready shifting of the location of the brush along theshaft on which it may be mounted. In connection with the foregoing I provide a novel construction of brush or brush section.

To the accomplishment of the foregoing and related ends, said invention, then, consists ofthe means hereinafter fully described and particularly pointed out in the claims, the annexed drawings and the following description setting forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of the various mechanical forms in which the principlefof the invention may be used. F

' In said annexed drawings Fig. 1 is a side elevation of my improved brush mounting showing a brush secured thereon; Fig. 2 is an exial section thereof,

taken on the plane indicated by the line 2-2, Fig. 1; Fig. 3 is partly a side elevation and P r y a redia f i realise four of My imsuch mounting, showing the shaft or arbor to which it is secured, but omitting the brush; Fig. a is partly an end elevation and partlyn transverse section. of such modified mount ng; Fig. 5 is an axial section showing a modified form of brush base or hub adapted for use with my improved mounting, a special construction of brush, or rather brush section, being likewise shown; Fig. 6 1s a sideelevation of such brush section showing detail construction thereof; F ig. 7 is a transverse section of such brush section taken on the plane indicated bv line .7-7, Fig/6; Fig. 8 is a view similar to Fig. 5. but showing the complete assembly of brush, hub and mounting therefor with shaft or arbor, the brush'being'of the special construction shown in Figs. 6 and 7; and Figure 9 1s a view similar to Figure 3 but show ing a modified form of mounting which is a combination of the forms used in Fi ures 2 and 3. I a

Inthe relatively simple form of construction, as shown in Figs. '1 and 2,-a broken section of a shaft or arbor 1 is illustrated. Upon this is fitted a sleeve 2 that is formed with a beveled flange 3 at itsone end," such sleeve being exteriorly' threaded. at its other end and formed with a plurality of l-o-ngitudmal slots extending from' such flanged end approximately to such threads on the other end. Rings 4 and 5' surround said sleeve, such ring 4; co-operating with flange 3, and said ring 5 being held in place by a suitable nut 6. Both rings are for-med with similarly inwardly directed beveled flanges 7 that are adapted to engage with complementary annular recesses 8 in the sides of the brush base 9. This base, and thus the brush as a whole, is formed in a plurality of segmental sections, (2 semi-circular sections as shown), so that when the rings 4 are sufficiently retracted so as todisengage'flanges 7- from recesses 8 in the brush base or hub, the sections of the brush may be separated and entirely removed. Similarly by bringing such sections together about the sleeve and forcing the flanges i and 5 together through the medium of the nut 6, said sections will be firmly locked in place upon the sleeve and present the effect of a continuous .r ng, by virt e o engag e t h he beveled flange 3 on the sleeve will cause the portions of the latter between the slots therein to press inwardly against the shaft 1, and thus firmly secure the mounting, together with the brush, in selected position upon such shaft.

The modified form of mounting shown in Figs. 3 and. 4 in general resembles that just described, but is in addition designed itself to be removable from the shaft or arbor 1. To this end the. sleeve consists of two or more longitudinally split sections 1O. The flange 11 at the one end of such sectional sleeve is correspondingly split and formed with inwardly projecting pins 12, and the (yo-operating ring 13 is likewise split and formed with apertures 14 disposed to regis ter with said pins 12. As shownin said Fig. 4 the sections of the ring 13 are angularly displaced about the sleeve sections so as to overlap the split in the letter. ,A. transversely split ring 1 3 is likewise proyided, said ring corresponding with ring of the previous construction, and cooperating with such ring is a second split ring 16, the sections of which are staggered with respect to the sections of said ring 15, andare formed with laterally projecting pins 17 disposed to enter apertures 18 in the sections of said ring 15. The. nut 19, whereby the sectional rings just described, are drawn together in assembling a brush on the mounting in quest-ion, is likewise ,otsectional construction, the parts being secured t-cgetherby means of inserted plates20 that are secured in place by screws 2-1.

The mounting just described, it. will be obvious, can be securedon a shaft without removing the same from its hearings, or disturbing other parts mounted thereon. In use, the brush is of course secured between the rings 13 and 15 justas it is between rings at and 5 in the previously described construction. The sleeve made up of the split sections 10 is secured against rotation on the shaft by means of a pin which is received in a suitable aperture in the body of the shaft as best shown in dotted lines in Fig. 37

In the form shown in Figure 9 the same sectional sleeve is employedas in Figure 3 but the end of the sleeve is provided with a iiai ,7 50 having a beveledtace 51. lhe inner ring is sectional as in Figure 3xbutis provided with a beveled face 53ndapted to ride on the face 51 ofgthesleeve'to lock the sleeve in place on the shaft. IToseeurethe sections of ring toget er they are provided with pins adapted to enter apertures in the flange 50, these apertures being slightly larger than the pins to permitthe movenent of the sleeve sections due to the cam act on ad acent the faces 51 and The term of mount ng shownin F gs. 5

.3l1li.8.;l$ designed te no way with. he. races sity of any base or hub, such as hub 9, on the brush, by substituting for rings 4: and 5 or 13 and 15 as the case may be, two specially formed rings 25 that are adapted to receive and directlysupport the brush 26. In other words, while such brush 26, is split transversely into segmental sections, so as to be reinovably mounted between rings 25, such sections are adapted to seat directly on the cylindrical faces 25 of said rings. The respective outwardly directed. faces 25 of the latter are beveled to co-operate with the flange 3 and nut 6 of the mounting proper, while on their inner faces said rings are provided with complementary retaining pins 27 and apertures 28, which serve to interlock the sections against relative radial movement. These .pinsserve the further purpose ofsecuring the sections of brush 26 in place by passing through suitably disposed aper- Y tures in segmental inwardly directed plates 29 securedinthe bases of such brush sections, as will presently be described. The rings 25-are furthermore provided with outwardly directed flanges 25 that are formed to bear against ,and laterally support the material composing the brush sections 26.

The detail construction of such brush sections, as shown in Figs. 6 and 7, involves thesuperposition of a plurality of segmental layers of brush material 31,1ooped about circularl v curved wires 32, with or without other filling elements. A line of stitching serves to hold the material in place upon such wires 32 pending the assembly of the layers to form a section of desired thickness. In such assembly, as best shown in Fig. 7, segmental spacing members 34 of pasteboard or equivalent material are preterably interposed between the successive layers adjacent their inner edges, these rings being first dipped in glue and then pressed together so that a unitary structure is provided after such glue is dried. In place of one ot' the rings 34, the segmental plate 29, previously referred to, is inserted at approximately the midpoint between the sides of the assembled section, and in order particularly to firmly secure this plate in place, as well as more firmly to bind together the coi'nponent layers and rings 34, one or more circular rows of broad-headed nails 35 are driven through the assembled body. of brush sections, suchnails being thus driven from opposite sides, adjacentv the wire rings 32, so as to penetrate more. or, less completely the successive spacing rings .34. These nails serve to strengthen the base of the brush and more firmly secure the brush material to such base, as-will be readily understood.

Other modes of applying the principle 0t my invention maybe employed instead of the one explained, change being made as regards the mechanism herein disclosed, arorideclitlie means stated byeny of the 1- nsvaaso lowing claims or the equivalent of such stated means be'employed.

I therefore particularly point out and distinctly claim as my invention 1. A mounting for a segmental cylindrical brush comprising a longitudinally split SlGBVG provided with a beveled flange adjacent one end and exteriorly threaded at the other end, anut on said threaded sleeveend, and annular members surrounding said sleeve between said flange and nut and adapted to engage the bases of brush sections.

2. A mounting for a segmental cylindrical brush comprising a shaft, a longitudinally split sleeve provided with a beveled flange adjacent one end and exteriorly threaded at the other end, a nut on said threaded-end, and annular members surrounding said sleeve between said flange and nut and provided' with inwardly directed flanges adapted to engage with the bases of the segmental brush sections, one of said members being adapted to ride up said beveled flange on said sleeve to clamp said sleeve to said shaft.

8. A mounting for a cylindrical brush comprising a longitudinally splitsleeve provided with a flange adjacent one end and teriorly threaded at the other end, a nut on 7 said threaded sleeve-end, and annular members surrounding'said sleeve between said flange and nut and adapted to engage the base of the brush.

5. The combination of a cylindrical brush consisting of a plurality of segmental sections, and a mounting therefor comprising a longitudinally split sleeve provided with a beveled flangevadjacent one end and eX- teriorly threaded at the other end, a sectional nut on said threaded sleeve end, and sectional annular members surrounding said sleeve between said flange and nut and adapted to engage the base of the brush.
